Today we have officially released the new SpamFilter ISP and SpamFilter Enterprise v4.0.1.783. This release is
available for download in the registered user area of our website. A free Evaluation copy is also available for all other users.

As always, this upgrade is free for all users with a current software maintenance.

There
are no major filtering changes in this release, but rather a number of enhancements and minor bug fixes.

As a side-note, build 783 carries two (very) minor fixes for two issues during a new installation of SpamFilter (upgrades were not affected). These two fixes are the only changes over the previous release-candidate build 782.

Following is the full list of additions/fixes since the previous official release 4.0.1.772:

// New to VersionNumber = '4.0.1.783';

{TODO -cFix : The SPF settings for neutral, softfail and fail had
the opposite values instead of the recommended defaults for new
installations of SpamFilter in empty directories}

{TODO -cFix : During new installations, in SpamFilter ISP the
"Custom Domain Filters" was not available due to an empty value in the
"LocalDomainsFilterMatrixFileName" entry in the SpamFilter.ini file}

// New to VersionNumber = '4.0.1.782';

{TODO -cNew : There was a limit of 65535 emails that could be
queued in the quarantine and the queue directories in case the DB or
the destination SMTP servers were offline. Stopped using the Windows
API to create temp files and are now using GUIDs to eliminate this
limitation}

{TODO -cNew : Use Windows Messages to update the real-time
activity log in GUI rather than creating a new thread to update each
line in the GUI memo control. Done to improve performance in high
traffic sites and to reduce number of threads used}

// New to VersionNumber = '4.0.0.774';

{TODO -cFix : When sending an NDR notification for a
non-deliverable email, if the NDR also has delivery problems, these
problems were note being logged, making it appear in the logs as if the
NDR was successful}

{TODO -cFix : SpamFilter could, in very rare occasions, freeze
when processing the cleanup of the IP Blacklist Cache Limbo blacklist
and the GreyList blacklist}

{TODO -cNew : Removed the logging of specific IPs being removed
from the IP blacklist and limbo caches to improve performance and
reduce risk of delays}

// New to VersionNumber = '4.0.0.773';

{TODO -cNew : Allowed to specify future dates in the
GreyListAllowed.txt files so that IPs can be stored in the list for
years without expiring}
